A Telegraph investigation can reveal that many more London 2012 Olympic tickets will go to the public than first thought.

While the London Olympic Games organising committee (Locog) has highlighted that, overall, 75 per cent (6.6 million tickets) tickets will be made available to the UK public, the numbers of Olympic tickets that will end up in the hands of the UK public will be about another half a million tickets, representing just over an extra five per cent.

This is because the public will end up with a small portion of tickets that have stemmed from other "pots" of tickets that make up the remaining 25 per cent of tickets.

This 6.6 million pot of tickets available to the public has formed the basis of the recent ballot. Money has been withdrawn from the successful applicants and people will be told of their success this week, with detail on the exact tickets received on June 24. About five million tickets have been sold in this stage, leaving large swathes of tickets available in the next round of ticket sales. The leftover tickets are comprised of football preliminary matches, hockey, basketball and handball games as well as expensive seats in more popular sports such as the heats of the athletics. Those who received no tickets in the first round of the public offer will, on a first come first served basis, have a second chance to buy some of the remaining tickets. This is estimated to be one million applicants.

In the public pot – 6.6 million tickets – 200,000 have also been distributed under a scheme called Ticketshare. These have gone to schoolchildren under the Mayor of London's scheme, 10,000 to Tickets for Troops and 5,000 to the British Olympic Association. The ticketshare scheme has been funded by a surcharge imposed on the premium and corporate hospitality ticket sales in order to keep faith with Locog's publicised line "there are no free tickets".

So where does the other 25 per cent go?

Twelve per cent of tickets – 1.056 million – are allocated to the 205 national olympic committees .These tickets are used internally by the committees for their national sporting bodies but most of the allocations go on sale for the public. This is how Germany received 50,000 tickets, Hong Kong 2,000 tickets and Jamaica 1,800 tickets. The BOA says its allocation from this pot – expected to be in the thousands – will be distributed to current athletes, to its national sports bodies, former athletes, and a small number for staff.

For instance one national sports body, the Royal Yachting Association will get around 2,500 tickets. Another, British Swimming, has ordered in excess of £80,000 of tickets which will go to personal coaches, support staff and also some long-serving volunteers.

"This is a great opportunity for key staff to see what the Olympics is all about," British swimming chief executive David Sparkes said.

Many of the sports cannot secure enough accreditations for their staff and use the tickets as a way of getting them into the Olympic venue. UK Athletics has ordered a six-figure value of tickets that will go to members of its supporters club and ex-Olympians, but also to personal coaches of athletes who are not accredited through Team GB.

There is another pool of tickets representing eight per cent – or 704,000 – which are sold to the 50 Olympic sponsors and stakeholders. Some of the stakeholders are interesting: they include 9,000 for the Government, another 3,300 for the City of London and the 32 London boroughs, who each have had access to 100 top class tickets.

One sponsor, Proctor and Gamble said it will give away 90 per cent of its sponsor tickets, £1 million of category C class tickets, to the public. Many other sponsors also have public activation campaigns for purchasers to win Olympic tickets.

Just one per cent of tickets – 88,000 – is available for the International Olympic Committee, heads of state and senior government officials such as Prime Minister David Cameron and London Mayor Boris Johnson. Also drawing from this pot of tickets are the 26 international sports federations, including world football authority Fifa. These federations have had access to tens of thousands of tickets overall, but 95 per cent of their ticket purchases have been to their own sport.

Another three per cent of tickets, around 264,000, have been bought by Thomas Cook for resale within the UK as packages with accommodation. A further one per cent, or 88,000, have been bought by the high end hospitality resellers JetSet Sports and Prestige Ticketing, who have been selling expensive packages in excess of £450,000.

Locog has also promised to find 70,000 further tickets to distribute to Olympic athletes so that two family members will be able to watch them during every session in which they compete. Swimmers, however, only have access to one ticket, although the BOA is trying to use some of its allocation to redress the balance.
